Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 150mm stroke and a built-in 4M210-06 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06A
The AirTAC SAIF40X150S-06A is a double-acting profile cylinder with an integrated 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78 and a 14.0 mm2 effective area. Driven by an AC220V terminal coil consuming 3.5 VA, it activates in 0.05 s. The integrated manifold uses an O8 x O5 PU tube to bridge the valve and cylinder, meaning the 1/8 valve port and 1/4 cylinder port serve distinct roles in the assembly. Because the valve operates at 0.15-0.8 MPa, the practical working pressure for this unit is 0.15-0.8 MPa rather than the bare cylinder's 1.0 MPa rating.
This unit produces 628N of push force and 528N of pull force at 0.5 MPa. It includes a magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Switching itself from a single coil signal, it eliminates remote valves and saves panel space for decentralized machine layouts.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06A Is Used
Decentralized Stations
Eliminates the need for a remote valve bank, allowing independent control across sprawling machine layouts using a single AC220V signal.
Space-Tight Machines
The built-in 4M210 valve and manifold block save valuable panel and tubing space in compact assembly cells.
Retrofit Automation
Ideal for upgrading older lines where routing new pneumatic tubing back to a central control is too costly or complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06A the Right Choice?
Choose this 40mm bore when you need more force than the 32mm version (402N push at 0.5 MPa) but want a compact footprint, stepping up to the 50mm bore (982N push) is unnecessary. The SAIF40X150S-06A is ideal when a self-valved cylinder beats running separate valve tubing across a large machine, cutting plumbing complexity. The 150mm stroke falls under the 300mm side-load threshold, so standard mounting handles the load without auxiliary guides. If the application requires holding a load without live air pressure, note that the 5/2 valve routes air but does not lock; consider an AirTAC SAIL lock cylinder instead. For exact replacements, match the 40mm bore, 150mm stroke, 06 (1/8) valve port, AC220V terminal coil, PT thread, and -S magnet.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF40X150S-06A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 valve provides a 14.0 mm2 effective area with a Cv of 0.78.
No, the integrated 5/2 solenoid valve handles switching directly. It operates on AC220V power. Factory-set to retract when energised, the valve can be repositioned to extend-when-energised.
